Insulators and Conductors Diagram | Quizlet

Electrical conductor

A material that conducts electricity well.

Electrical Insulator

A material that DOES NOT conduct electricity well.

Wood

A good electrical insulator/ a poor conductor

fabric

A good electrical insulator/ a poor conductor

series circuit

An electric circuit with a single path

circuit diagram

the way to draw an electric circuit that includes a power sources, wires and a load. Each part is labeled.

parallel circuit

A circuit that contains more than one path for current flow.

open switch

current CANNOT flow

closed switch

current CAN flow

battery

a type of power source in a circuit

insulator example

a rubber band

Conductor example

metal key

Conductor-bulb

allows electrical energy to pass so the bulb is lit

Insulator-bulb

does not allow electricity to pass so the bulb it not lit

examples of insulators

glass, plastic, wood, rubber, sand, dry air, cloth

example of conductors

iron, copper, silver, gold, aluminum, water

Open Circuit

the rubber band does not close the circuit

Closed circuit

the key closes the circuit and allows electricity to flow.

circuit

a path for an electrical current to flow around

open/break in the circuit

an incomplete electrical circuit in which no current flows because there is a gap

series circuit

An electric circuit with a single path

closed/complete circuit

a complete circuit with NO GAPS through which electricity flows

Copper

a VERY GOOD electrical conductor of electricity used in wires

Plastic

a GOOD electrical insulator used to coat wires

Metals

Generally good electrical conductors - but some are better than others
